An oll-driling company must choose between two mutually exclusive extraction projects; and each requires an initial outlay at t=0 of $13 million. Under Plan A, all the oil would be extracted in 1 year, producing a cast flow at t=1 of $15.6 million. Under Pian B, cash flows would be $2.31 milion per year for 20 years The firm's WACC is 12.6%. a. Construct NPV profies for Pans A and B. Enter your answers in militions. For example, an answer of $10,550,000 should be entered as 10.55. If an amount is zero, enter " 0 ". Negative values, If any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to two decimal whacas Identify each project's IRR. Do not round intermediate calculations. Round your answers to two decimal places. Project A: % Project B: Determine the crossover rate. Approximate your answer to the nearest whole number. b. Is it logical to assume that the firm would take on all avallable independent, average-risk projects with returns greater than 12.6% ? Identify each project's IRR. Do not round intermediate calculations. Round your answers to two decimal places. Project A: Project B: Determine the crossover rate. Approximate your answer to the nearest whole number. b. Is it logical to assume that the firm would take on all available independent, average-risk projects with returns greater than 12.6% ? If all available projects with retums greater than 12.6% have been undertaken, does this mean that cash fows from past investments have an opportingity cost of only 12.6%, because all the company can do with these cash flows is to replace money that has a cost of 12.6% ? Does this imply that the WACC is the correct reinvestment rate assumption for a project's cash flows
